This model is designed to be printed with no supports. The two “holders” that are on the sides of the box are designed to be friction fitted, but some glue may be necessary.
Please keep in mind that the “locker” should be printed before the “top” since halfway through the print you insert the “locker” print to keep it in place. Other than that, it should be easy printing!
Enjoy!
